Just wondering what formula's other people had luck with?

DD was on S26. She is pretty unsettled so the Doc said try soy formula. So we tried S26 Soy. Not much of a difference, but mabey less vomiting (shes a big chucker!!)
So after about 3 weeks we are back on S26 not differnce again, but now shes vomiting all the time again. shes has to have new clothes every few hours. I dont really mind the chucking, its just gross, and must not be very nice for her!

Any suggestion on formulas that worked for you?

Thanks
